' DUST-SEPARATING TANK.

Specification of Letters llatent.

Patented Nev. 1.' 1910 Application vtiled April 1,' 1909. Serial No. 487,278. l

My invention has for its .object the ro- 15 duction of an apparatus by means of w ich the dust and dirt drawn into it by a suctionpu'mp or vacuum-inducing 'apparatus is collected therein, and so that `thelren'ioval of dust and dirt can be accomplished conveniently-and'with despatch.

' It'als'ov hasfor' its object the production of a 4simple and inexpensive apparatus in which 1all'partsrare easily accessible 4for removal or cleaning.

Another'object' is the provision of suitableV means for. withdrawing in bulk `the coarser particlesof dust and dirt collected therein, and tootherwise improve on apparatus of this type. v

To these ends my invention consists in the construction, arrangement, and combination of parts to be hereinafter described andl particularly ypointed out in the appended claims.

In the drawings- Figure 1 is a. vert-ical longitudinal section of my apparatus showing a portion of the connectlons to a cleaning orrenovatingtool andl to a suctionpumpA or vacuum-inducing apparatus. Fig.

40 2 is a horizontal section taken on line w-,

tion takenon linealy, Fig.' 1.3` Fig; '4 is a itran'sverse section taken online -z, 1. Fig. 5 is a detached perspective view of the clamp-frame' for clamping the canvas sack in position. Fig. 6 is adetached perspective view of a cross bar coperating with said. Aclamp-frame. F ig. 7 is a detached perspective view of the removable head whereby the interior of the apparatus is rendered accessible `l Referring now to the drawings in detail,

corresponding numerals of reference refer to corresponding parts in the several figures.

The reference numeral 8 designates-the shell or casing provided with an inlet its top wall to which is threadedor otherwise secured a fitting l0 for connection thereto of a fiexible or other tube, or tubes 11 having connection Vwith a. pneumatic cleaning or renovating-tool in vthe usual manner. 'I have herein shown two flexible tubes 11, but one or more than two may be used if desired, it being only necessary to change the fitting 10 to accommodate the desired number' ot' tubes. The casing is also provided with an outlet 12, havin nected thereto a pipe 13 which leadgs to a suction-pump or other vacuum-inducing apparatus. Said casing is open at one end and a closure or head 14 is removably held to 't said open end, it. having its edges provided with notches 15 through which swinging bolts 16 pivotally secured between lugs 17 formed on the casing are held. Thumb-nuts 18 are threaded onto said bolts so lasto clamp said head or closure tightly against the open end of the casing. Right-angular strengthening-ribs 19 :1re formed on said head or closure and `so arranged that the notches 15 extend through the ends of the same, as best shown in Fig. 7, and a handle 20 arranged centrally on said head or closure provides a convenient means for handling the same. l

The casing is provided internally with a bearing flange 21, preferably continuous, and a gasket 22 is held against said bearingflange. A screening-device or canvas sack 23, or other like or foramino'us material preferably in the form of a sack, has its vmarginal or edge-portion at its open end .clamped against said gasket, as at 24, by

means of'ja clamp-plate 25. Said plate '1s preferably of rectangular form and pro vided with large openings 26 and a solid center 27. The particular form of clam-pplateherein shown comprises side-bars 28 and cross bars 29 arranged at right-angles to intersect at the center and thus provide the solid center 27 above referred to.

Cooperating with said clamp-plate is a pocket 32 formed in an extension 33 of the casing; said pocket being of siitlicient depth to permit the cross-bar to be moved length-I wise-so thatthe end placed behind the lng or ear 31, will clear the same and permit the cross-bar to be conveniently removed.A In

thus positioned, the other end of said barclears said lug or ear and can he swung into,

a plane behind the saine after which the bar can be moved lengthwise to have said end positioned behind said lng or ear, yet retaining the opposite end in the pocket In order that one 'end o the bar can be coni-'eniently inserted in the pocket 32 williout striking the lug or ear 3l, said pocket is made eon'iparatively high, thus perinitting the bar to be inclined while inserting the saine and thereby bringing its opposite end above the lng or ear until after the firstmentioned end is properly inserted in the pocket 32.

Passing centrally through said bar, -is a clamping-screw 34 having preferably a conical end adapted to lit into a corresponding depression formed in the solid center of the clamp-plate. 'lVhcn the end of the clamp-screw is forced against the elainpplate, the Cross-bar 3() is. forced againstthe front Wall of the pocliet 3L- and against the rear face of the lng 3l, tlfis providing a rigid support for said cross-bar 'so that the clamp-plate may be forced against the edge of the sack with proper pressure to clamp it in position.

Resting upon the bottoni olf the easing is a dust or dirt-receptacle 3(3,to which is pivotally secured a vertical screei'i 37 extending rom the top ot said .receptacle to the top wall of the easing. iiid it i'or any reason access isidesired tofttlni tank behind said screen, itrjs only necessary to remove the closure or li'ead ift and swing the screen 37 into a horizontal positibn 'so that'itcloses the top of the receptacld 36. The dust and dirt drawn into the casing by action of the suction-pump or vacuuiii-inducing`appara- ;tus, strikes the screen 37; the coarser particles unable to pass tlitjough the meshes oli said screen dropping in'to the receptacle 3G, while the .tiner particles pass through the screen and are drawn rearward against the rear wall of the canvas sack 23, the air passing through the canvas @and leaving the dust behind,'which then falls to the bottom of the sack. c

In order to prevent collapse vof the rear end of the sack, a wire frame 38 of an suitable construction is sewed thereto. fine screen 39 covers the outlet 12 of the cas i the side walls and its other end fitting into a i ing so that `in theevent of the sack becoming t torn, the dust will not be drawn into the .suction pump or vacuum -influcing apparatus.

'l`lie casing is provided with sight-openii'igs 4() vfitted willi small panes-oic glass in an air-t ight manner so 'that the operator can ascertain when the receptacle 3G is filled with dust oi' dirt.
